Abstract
In an underwater sensor array system, various types of piezo-electric transducers are used for generang and receiving acousc waves. To generate acousc waves underwater, sonar systems predominantly use PZT based electro-acousc transducers in the form of arrays housed inside a sonar dome. The transducers and thus the arrays in the system have their frequency dependent beam paern, voltage response and acousc receiving sensivity aributed to their design. The characterisc behavior of transducers is evaluated experimentally by carrying out underwater evaluaon at desired depth in stac water as per standard …Read More
